Integrated Circuit Chip SAA7105H/V - NXP Semiconductors - Digital video encoder



Detailed Product Description

Quick Detail:


Digital video encoder





The SAA7104H; SAA7105H is an advanced next-generation video encoder which converts PC graphics data at maximum 1280 × 1024 resolution (optionally 1920 × 1080 interlaced) to PAL (50 Hz) or NTSC (60 Hz) video signals. A programmable scaler and anti-flicker filter (maximum 5 lines) ensures properly sized and flicker-free TV display as CVBS or S-video output.

Alternatively, the three Digital-to-Analog Converters (DACs) can output RGB signals together with a TTL composite sync to feed SCART connectors.





Digital PAL/NTSC encoder with integrated high quality scaler and anti-flicker filter for TV output from a PC

• Supports Intel Digital Video Out (DVO) low voltage interfacing to graphics controller

• 27 MHz crystal-stable subcarrier generation

• Maximum graphics pixel clock 85 MHz at double edged clocking, synthesized on-chip or from external source

• Programmable assignment of clock edge to bytes (in double edged mode)

• Synthesizable pixel clock (PIXCLK) with minimized output jitter, can be used as reference clock for the VGC, as well)
